Given numbers are 447,137,672,276,920

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 447,137,672,276,920 is 1577516640.

Find LCM of 447,137,672,276,920 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 2 x 3 x 23 x 149 x 137 x 28 x 1 x 5 = 1577516640

Therefore, the lowest common multiple of 447,137,672,276,920 is 1577516640.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

447 x 137 x 672 x 276 x 920 = 10449470223360

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

447 : 1, 3, 149, 447

137 : 1, 137

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,137,672,276,920, is 1.

Now, the common factors can be found like this.

447:3x 149

137:137

672:2x 2x 2x 2x 2x 3x 7

276:2x 2x 3x 23

920:2x 2x 2x 5x 23

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 2x 2x 3x 3x 23 = 6624

Therefore, the value for common factors is 6624.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 10449470223360/(1x6624)

LCM = 10449470223360/6624

LCM = 1577516640

Thus, we can understand that the LCM of 447,137,672,276,920 is 1577516640.
